14 | # $cmddef defines which (sub)commands are available in a specific CLI class. | |
15 | # A real command is always an array consisting of its class, name, array of | |
16 | # position fixed (required) parameters and hash of predefined parameters when | |
17 | # mapping a CLI command t o an API call. Optionally an output method can be | |
18 | # passed at the end, e.g., for formatting or transformation purpose. | |
19 | # | |
20 | # [class, name, fixed_params, API_pre-set params, output_sub ] | |
21 | # | |
22 | # In case of so called 'simple commands', the $cmddef can be also just an | |
23 | # array. | |
24 | # | |
25 | # Examples: | |
26 | # $cmddef = { | |
ca3269f4 | 27 | # command => [ 'PVE::APIClient::API2::Class', 'command', [ 'arg1', 'arg2' ], { node => $nodename } ], |
565bbc73 | 28 | # do => { |
ca3269f4 | 29 | # this => [ 'PVE::APIClient::API2::OtherClass', 'method', [ 'arg1' ], undef, sub { |
565bbc73 DM |
30 | # my ($res) = @_; |
31 | # print "$res\n"; | |
32 | # }], | |
ca3269f4 | 33 | # that => [ 'PVE::APIClient::API2::OtherClass', 'subroutine' [] ], |
